Forbes.com's latest ad campaign, launched this week, asks users to "Take The Forbes.com Challenge." The campaign combines Forbes.com's Brand Increase Guarantee with a sales initiative introduced last
year comparing the value and impact of online advertising - specifically on Forbes.com - with advertising in traditional news media, including the print version of The Wall Street Journal. The
campaign will run in print and online with Advertising Age, AdWeek, BtoB magazine, medialifemagazine.com and MediaPost's sister publications Media magazine and MediaDailyNews. Spending was not
disclosed.
